A Light Bar – Square Series, also known as a Square LED Light Bar or Square LED Indicator, is a compact LED display component used for visual indication in electronic products, control panels and industrial equipment.
Unlike numeric displays or dot matrix displays, a square light bar is mainly used for simple visual indication. It helps communicate status, signal, mode, alert, operating condition or equipment function through an illuminated square display area.
Alfa Electronic Components supplies Square Series LED Light Bars for industrial electronics, embedded systems, machine panels, electronic instruments, control panels and custom LED display assemblies. The range includes multiple square body sizes for different panel designs and visibility requirements.
Square LED Indicator Format
The square format gives the product a clean and balanced appearance on front panels and electronic equipment. It is useful where a simple illuminated square indicator is required instead of a numeric digit, arrow, bar graph or text display.
This format can be used to indicate:
- Power status
- Machine status
- Signal condition
- Operating mode
- Warning indication
- Active/inactive function
- Equipment condition
- Control panel status
- Process status
- User interface indication
The final indication style depends on the selected model, LED color, circuit design and front-panel arrangement.
Available Square Light Bar Sizes
The range includes six body sizes:
- 10 × 10 × 8.5 mm
- 15 × 15 × 11 mm
- 22 × 22 × 11 mm
- 27 × 27 × 11 mm
- 32 × 32 × 11 mm
- 40 × 40 × 11 mm
The smaller sizes such as 10 × 10 mm and 15 × 15 mm are suitable for compact PCB-mounted indicators and small electronic products.
The medium sizes such as 22 × 22 mm and 27 × 27 mm are suitable for control panels, equipment interfaces and industrial electronic devices.
The larger sizes such as 32 × 32 mm and 40 × 40 mm are useful where the indication must be more visible on equipment panels or operator interfaces.
Single Color Indication
This Square Series Light Bar range is available in single color format. It is suitable for applications where one consistent LED color is required for indication.
Buyers should confirm the required LED color, brightness, electrical configuration and availability before finalising the model.
PCB Mount Indicator Component
These light bars are suitable for PCB-mounted applications. The selected model should be checked against the PCB layout, enclosure design, panel opening and required viewing area.
Because light bars are often used in front-panel indication, buyers should confirm the body size, visible area, pinout, electrical connection and latest approved technical drawing before PCB design or production.
Suitable for Industrial and Electronic Indication
Square LED Light Bars are commonly used in industrial equipment, control panels, electronic instruments, power systems, machine interfaces, embedded devices and custom indication panels.
They provide a simple and effective visual indication method where the user needs to identify status or function quickly.
